To all whom may concern veutcertain new prior application ing or fire-polishing of glass-ware; `machine; generally speaking, constantly revolving frame, properly heated openings,

v L' ticles to the furnace openings,

' I. glass-handling devices,

Be it known that-THEoDoRE STEIIIER, deceased, a ,citizen of the United States of A.me1'ica,`\vho resided in the city of Plttsburgh, 'county of Allegheny, and `State of .'Pennsylvania, did during his lifetime inandy useful Improvements in Glass-Handling Apparatus, of which thev following is a specification.

This application, which is a division of a o. 543,582, has K n'i'echaliism shown and embodied in a machine adapted for the described therein, and

glaz- This a and glass-hanthe glass arboth mounted on and moving with the frame, and transfer devices for receiving the articlesfrom a fixed delivery station, and for positioning them where they may be taken up by the dling devices' for presenting from such levices and delivering them to a fixed receiving station. n1sms,wh1ch per' se, constitute an important feature of this 1nvent1on,

and. so may be held stationary at times. During .the latter period, they are successively in registration with stations. During the period during which they move with the frame, they are in such cooperative position ing mechanisms as to deliver to the latter, or toreceive therefrom, the article under treatment, while the motionuof the transfer devices in respect to the traveling frame re` filed Feb.' 12,1910, Serial for its object to claim a comprises a furnace w1thv and for taking them'` The transfer mechaf both move with, f' and move relatively tothe' revolving frame,

one of the fixedl with the glass-support-l whereby such' first 'Y load before it again passes the loading station. The article'transferred from the first part is carried past the loading. station on the other. part,-and.is then discharged. This overlap prolon'gs the period in which the articles can. be retained in the machine the capacity thereof due to slowing down its cycle. This feature of my invention is independent of the stoppage of the parts at the stations for loading or unloading.

The invention further consists in the conwhich it is composed,

the )several parts of described as will be hereinafter more fully and claimed. f

Referring to the accompanying drawings, in which corresponding parts are-designated by corresponding marks of referencer Figure 1 is a vertical 'central section taken on line l--1 of Fig. 4 of a lire-polishing de.- vice embodying this invention.

Fig. 2 is a partial section and'plan on the line 2-2 of Fig. 1, showing the'means for operating the i holder ,carrying the article during the) fire polishing.

Fig. 4 is a plan view of the table of Fig.. 1, and :if-section on' line 4-4 thereof.

-Fig. 5 is a side elevation showing in detail, the transporting or take-'off devices, appearing in plan at the left of- Fig. 4.

The invention .in the embodiment here shown, includes `ahrc-polishing furnace (which maybe .of a known construction), and glass-handling devices for placing and holding the glass the glory holes 113 thereof, all mounted forcontinuons rotation around a central vertical axis on a table 1'15.

On the frame.or standard 114, I mount ia table 115 which is continuously rotated by a bevel gear 116 and a pinion'117 on shaft articles in, or opposlteto without reducing i struction, arrangement, and combination of 118 whichfby gears 119 and shaft1120is conl nected in any convenient way with a .main

.power shaft. The fire 'is furnished byy a 4burner 121-in the center 'of the frame4 114, entering the throatY 122 of the furnace 112, andthis latter issupported oni-the 'rotating table 115 as hereafter described. An extension 123 of the frame 114, carrying a fixed cylinder 124. 'supports fixed cam plates 125,

' 126 and 127.' All the other parts of the machine revolve. The revolving table 115 is provided around its vouter edges withv studs 128 supporting a plate 129 which in turn carries a series of stationary blocks 143 and stanchions 150 supporting plate 151, and the latter in turn carries supports 152 for the furnace 112.

Between two dependent lugs 153 fixed on the plate 151, I provide a series of lifters Shown in front elevation. in Fig. 3. Each consists of a lifting device or box 131 pivoted on pins 132 and containinga series of rollers 133 mounted therein in inclined semi-circu-l lar arrangement and driven through intermeshed gears 134 by a system of gearing 135 driven from shaft 136 which in turn is rotated by the rack 137 -ixed oli an extension 138 of the fixed frame 114.

At points spaced around the axis about which the furnace revolves is a delivery table 110, and a receiving table 168, while carried at the periphery of the revolvingv base plate 115 are a series of article supports ots 132, it stands behind the tumbler 111 and 160, each capable vof being respectively brought to rest opposite and adjacent to t e respective tables in their passage thereby, and having for this purpose a limited circumferential movement in respect to the base plate. A glass article, shown in thel drawing as a tumbler T, can be shovedeither by hand or by ap ropriate timed mechanism from 'off the delivery table to the support 111 'opposite that table, or can be pulled off the support 160 opposite the receiving table onto that table.

Itrwill be seen from Fig. 1 that when `the box 131 hangs vertically down from its ivthe rest 111. By means of a rack 140 in the plate 129, engaging a. gear 141 on the pivots 132, the box is swung up to thehorizontal position shown in dotted lines in Fig. 1, in which motion it passes-around the rest 111 and receives the tumbler T, (as will be plain from Fig. 1) and carries it up in line with a holder 142. This motion of the rack 140 is imparted by the engagement of a dependl ing stud roller 140 engaging the cam slot 127 in the fixed plate 127. A plan view of lsh'is rack 14() in the plate 129 is shownin 1g. 2. v 4 i Placed parallel with each rack 140 and to the plane of movements of its lifting box 13 1,

- there are'fixed blocks 143, in which 1s guided an oscillating block 144 pivoted on a trunnion 144n in a air of the lstanchions 150. This block .144 as a forwardly extending tubular by the engagement of the pin extensions 148Il onarm 148. The arm 148 is pivoted on the next block 143 and it has a roller stud 149 which engages a cam slot in the fixed plate 126, above, as will be evident from Fig. 1. This shores the stem 146l and its holder plug into the tumbler when it'is in horizontal position, and then, by the engagement of a gear 154 on the shaft 144*l with a reciprocating rack 155 set in the plate 151, the tumbler is swung up into vertical position within the glory hole 113, aS indicated in dotted lines at the left of Fig. 1. The rack 155 is moved by the engagement of roller stud 156 with a cam slot 1n the fixed plate 125. Meantime, the arm 146 of the holder plug is rotated by a pinion 145 engaging an idler 145- sur-` rounding the trunnion 1,44*L and driven by a pinion 157 on shaft 158, which in turnA is driven by means of rack 159 also fixedly mounted on the base extension 138 which carries the rack 137.

While the tumbler is in the tire of the glory hole, it will be observed thaty the edge of the tumbler next the fire is in a vertical sition to avoid any distortion, and that 1t is rotated so that it is .heated evenly all over. Bythe time the. machine is rotated another 120 degrees or any other desired distance, the cam slots reverse the motions just described; the supporting arm 146 lowers toa horizontal position and deposits the tumbler again in the revolving rollers 133 of the lifting box 131, and eventually this returns to verticall position leaving t-he tumbler on the rest 160 as shown at the left of Fig. 1. The tumbler in handling has been constantly operated on to keep it moving and maintain its shape, it being understood that the rollers 133 will in each case l be made to exactly itthe sides of the article being made. The tumbler is now linished and is carried into the leer as hereinafter explained. v

Coming now to the horizontal movements ofthe 'supports for the tumbler; it will be 110 seen from igs. 1 and 4 that these supports 111 land 160 are carried on sliding blocks or partial ring sections 161 which are set on the revolving table 115 and are free to move. Referring to Fig. 4, es cially, these tumbler 115 supports are arrange in pairs, there being -one of each kind on each of the blocks or partial rings l161. It is necessary not only to bring them into register with the table 110 intermittently, and leave them station- 120 ary for a moment, but also necessary to alternate their osition .under the lifting de vices 131 andp 142, w ich are continuously moving around the machine. For this purpose vvImount upon the traveling table 115 a 125 H.series of transporting arms 162 pivoted at 163 and by means of a slot 164 engaging a pin on the sliding block 161. The end 165 of each arm'162 projects beyond the circumference of the table 115 and as it arrives 130 near the position of table 110, so that the support 160 is in position t'o receive the tumbler, it' strikes a stationary lug 166 'which prevents its further motion until the tumbler has been put in place ,and the end 165 slides past the fixed lug 166. Vlien this escapementhappens,the block 161 is again carried along with the table. 115 so that the tumbler support 111 is in register with .the lifting devices as before described. While the tumbler is being transported and treated in the glory hole, thei'eceiving holder 160 is 110 it is stopped in register therewith,

being' finished has been carried from about marked X in Fig'. 4 to the deat the left of the figure. But passes the table and when the receiving support "160 arrives at the position livery point whenever the support 11'1 '.the' position opposite the receiving table v168 at the left of Fig. ,4, it is stopped in register therewith. But immediately thereafter, the arm 162 strikes' another fixed lug 169 and shifts the other holder 111 into line with thelifting devices. Meanwhile-the carrier arm 1,7 0 takes the tumbler off support 160 at the opposite side of the table, and shoves it across the table 168 by means of the reciprocating'motion of a lever arm 171 engaging the sliding block 172 in the slotted table 173. The arm 171 is moved by a pin-and-slotening 1 7 5 from the power shaft .118. The lat'- eral motion ofthe carrier arm`170, necessary to enable it to .go behind the tumbler on the rest 160, is attained-byl pivoting on the block 172 a frame 176 immediately supporting the carrier arm 170, and thisframe is swung on its pivot. by engagement of'i'oller stud 177 with a camj switch 178' on the table 173.

The .frame 176 is returned to normal position by 'spring 179.

-The mechanism for moving the article from off the loading table 11() and onto thef 'rest 1,11 may consist of a slotted lever arm 107 reciprocated by a wrist-pin on a rotating V ing` table 110` is moved over onto .the sup" -port 1:11 standing opposite 'such table,

disk 108, and actuating a shove bar 109 pivoted'thereto. p y

The operation ofthe device is as folloWs,- A tumbler placed at one end'of the load- -the holder 160. This does'not.

agement with a disk 174 operated by gear' and in from of ai@ iiaingbox isi. The naar is then moved outwardly and upwardly b v movement of rack 14() and it straddles oveil y support 111, picks up the tumbler in the nest of' rcvolving'rollers 133, lifting it to a hori zontal position, while the .plug 142 is projected outward into the tumbler and immediately lifted by operation of rack 155 and laces the tumbler inthe glory hole 113. As 1t travels around with the' furnace 112 it is constantly rotated by the pinion 157 and its driving shaft158 engaging the fixed rack and exposed on all sides to the flame.

At the proper time, 'the tumbler is again lowered by the same agencies and deposited on the rest 160 which has meantime been shifted into therelative position formerly occupied by the rest 11 1,-,throiigh the agency of lthe shifting arms 162 moving slidingl blocks 161 when struck by the fixed lugs 167. AAs the rest 160 with the tumbler comes stopped by lug 169and shoves the tumbler across the table 168.
